Abstract

Laminated felt sheets, and assemblies thereof, having utility for impact absorption, ballistic resistance, penetration resistance per se, as well as in spall shields, structural composites and other applications.

Description

Laminated felt articles
Background of invention
1. invention field
The present invention relates to lamination felt and assembly thereof, described lamination felt and assembly thereof are because impact absorption own, bullet-proof, anti-penetration and useful and can be used for spall shield, structural composite material and other application.
2. description of Related Art
The lorica structure that is used for personal protection is remote but not outmoded technology.Metal armor has been well-known at 1500B.C for the Egyptian, uses up to general the 17th century end always.Recently, because the discovery of novel powerful fiber such as aromatic polyamides, High molecular weight polyethylene and polybenzoxazole (polybenzazoles), it is practical that lorica becomes again.
Known various fiber reinforcing texture is used for shock resistance, shellproof and penetration resistant articles such as the helmet, protective plate and vest.These goods showed different anti-thrusts the impact penetrability of utensil such as cutter and nail or projectile such as bullet, shell, shrapnel, glass fragment etc.
Shellproof and/or the penetration resistant articles that comprises by the high strength fibre of material preparations such as High molecular weight polyethylene, aromatic polyamides and polybenzoxazole is known.Referring to as United States Patent (USP) 6,534,426,6,475,936 and be entitled as E.I.duPont De Nemours International S.A. 1984 open of " Lightweight Composite Hard Armor Non ApparelSystems with T-963 3300 dtex DuPont Kevlar 29 Fibre (adopting the heavy armoring non-clothing systems of light composite material of T-963 3300dtex DuPont Kevlar 29 fibers) ".Described fiber can be woven or non-woven.That non woven fibre can be is knitting, single shaft arrangement or cross lapping or play felt.According to the feature of its structure and material therefor, this goods are pliable and tough or firm.
USP 4,181, and 768 have described the rigidity plate armour by extruded lamination 6,6 nylon membranes and the preparation of PPTA fabric alternating layer.Described fabric can be non-woven, as Nomex.USP 5,343, and 796 have described the armor system that comprises the first flexible fibre layer and the second soft cut-resistant fiber layer.The second layer comprises uncoated Nomex.U.S. Patent Application Publication 2002/0106956 has been described textile article, and described textile article comprises at least two kinds of kinds of fibers: a kind of toughness is 10g/d at least, and another kind of toughness is less than 10g/d.The layer that described fabric has that opposing thorn, snake are stung, sharp keen branch etc. punctures also can have microporous film layers after described anti-puncture layer.Described anti-puncture layer can be Nomex.
U.S. Patent Application Publication 2003/0022583 has been described ballistic fabric, and described fabric comprises the material of two types of fibers at least that mixes and be combined together to form the individual layer composite.Described fibrous material is by acupuncture and extruding and combination.H.L.Thomas is at the 14 ThInternationalConference on Composite Materials, July 14-18,2003, San Diego has discussed " Needle-punched Non-woven Fabric forFragmentation Protection the needled fabric of protection (be used to break) " in the showing material of CA.
Although confirmed several mechanism, the penetration performance complete analysis of fibre reinforced composites still surpasses existing force.The small cusp projectile can not make it fracture by horizontal replacement fiber and penetrates plate armour.In this case, penetration-resistant depends on that fiber can be pulled to the easy degree on next door, thereby depends on the feature of network of fibers.Key factor is the fastness of tissue or the friction of stagger(ed) cycle, yarn and fiber Denier, fiber and fiber in the cross lapping unidirectional composite material, matrix characteristics, plunger bond strength and other.The point fragment can penetrate by shearing fibre.
Early stage structure has several defectives.The cross lapping unidirectional fibrous composite materials is usually than better by the woven fabric ballistic performance of allied fiber preparation and weight is lighter, yet their prepare more expensive usually.Above-mentioned each structure has been brought the progress towards its target.Yet, there is not a kind of concrete structure of having described laminated material of the present invention and assembly, and all requirements that do not have a kind of the present invention of satisfying to satisfy.
Summary of the invention
The present invention includes lamination felt and assembly thereof, described lamination felt and assembly thereof are because impact absorption own, bullet-proof, anti-penetration and useful and can be used for spall shield, structural composite material and other application.Shockingly be that the performance that structure of the present invention back face deformation when being subjected to projectile and impacting unexpectedly reduces and provides the anti-lancet device of improvement to penetrate is provided.
In the embodiment, the present invention is independent laminated material, and described laminated material comprises: comprise the compression felt that two sides and the high strength fibre that is equal to or greater than about 17 gram/dawn (g/d) by one or more toughness of measuring according to ASTM D2256-02 are substantially formed; Be adhered to the plastic foil of side of described felt or two sides; And choose jointing material between described side and plastic foil wantonly.

Detailed Description Of The Invention
Be used for high strength fibre shellproof and/or the anti-penetration structure and prepare by complicated approach, itself is expensive and also can be used for other application as rope, commercial fishnet, tire cord and various reinforced plastics product, and is dual-use. When military demand was high, production capacity can not satisfy all demands. Because production capacity can not improve fast, so need to more effectively utilize limited amount high strength fibre supply. The resource of so far bottom line exploitation is the short fiber bag, and they are that all fibres production process is not intended to produce because of fracture or other problems. The short fiber bag is unwanted for woven or pre-preg operation. Yet the fiber in these bags can be advantageously used in the felt structure.
The present invention includes new lamination felt and assembly thereof. In the embodiment, the present invention is independent laminated material, and described laminated material comprises: comprise the compression felt that two sides and the high strength fibre that substantially is equal to or greater than about 17 gram/dawn (g/d) by one or more toughness of measuring according to ASTM D2256-02 form; Be adhered to the plastic foil of side of described felt or two sides; And choose adhesive between described felt and plastic foil side wantonly.
Shockingly, find the performance that laminated material of the present invention and assembly back face deformation when being subject to the projectile impact unexpectedly reduces and provides the anti-lancet device of improvement to penetrate. The water that laminated material of the present invention absorbs when immersing also lacks than the water that felt material absorbs.
With regard to target of the present invention, fiber is elongated body, and its length dimension is more many greatly than width and thickness lateral dimension. Thereby the term fiber comprises long filament with regular or irregularity cross section, band, bar etc. Yarn is the strand that comprises many fibers or long filament.
The toughness that the high strength fibre that preferred group becomes laminated material felt of the present invention is measured according to ASTM D2256-02 is 25g/d at least, more preferably 30g/d at least, most preferably 35g/d at least.
